Description

Door locking device for emergency escape of bus

본 발명은 버스의 도어가 자중에 의해 닫히는 것을 방지한 버스의 비상탈출을 위한 도어 록킹장치에 관한 것이다.The present invention relates to a door locking device for emergency escape of a bus which prevents the door of the bus from being closed by its own weight.

일반 시내버스의 경우 중간에 위치한 슬라이드 식 자동 개폐 도어에는 비상시 수동으로 조작할 수 있도륵 비상조작레버가 부착되어 있다.In the case of general city buses, the sliding automatic opening / closing door located in the middle is equipped with an emergency operation lever for manual operation in an emergency.

만일 이 비상조작레버를 오픈시키면 수동으로 슬라이딩 도어를 여닫을 수 있어 승객이 하차할 수 있게 된다.If the emergency operation lever is opened, the sliding door can be opened and closed manually so that the passenger can get off.

그러나 도1에 도시된 것과 같이 버스가 오르막 경사면에서 멈춰 섰을 경우 비상조작레버를 조작하여 수동으로 슬라이딩 도어를 열더라도 도어의 자중으로 미끄러져 다시 닫혀 버리게 된다.However, as shown in FIG. 1, when the bus stops on an uphill slope, even if the sliding door is manually opened by operating the emergency operation lever, the bus slides to its own weight and closes again.

도2는 도1에 도시된 것과 같은 상황에서 차실내에서 도어가 자중에 의해 닫히는 과정을 나타낸 것이다.FIG. 2 illustrates a process in which a door is closed by its own weight in a vehicle in the same situation as shown in FIG. 1.

이러한 경사면에 차가 정차되어 위급한 상황이 발생하게 되면 도어가 자중에 의해 자주 닫혀 짧은 시간에 승객이 안전하게 대피하는데 어려움이 있으며 대피중 다른 사고의 위험도 따르게 된다.When an emergency occurs due to a vehicle stopped on such a slope, the door is frequently closed by its own weight, which makes it difficult for passengers to evacuate safely in a short time, and also the risk of other accidents during the evacuation.

본 발명은 경사면에서 정차한 차량의 도어를 수동으로 오픈 시킬 때 오픈된 도어가 자중에 의해 다시 닫히지 않도륵 함으로써 승객이 안전하게 탈출할 수 있도록 한 것을 기술적 과제로 한다.The present invention provides a technical problem that allows passengers to escape safely by opening the door of the vehicle stopped on the inclined surface manually so that the open door is not closed again by its own weight.

도1은 종래 일반버스가 경사면 등판시 비상 정차한 상태도.1 is a state in which the conventional general bus emergency stop when climbing the slope.

도2는 도1의 상태에서 종래의 도어가 자중에 의하여 닫히는 상태를 나타낸 구성도.2 is a configuration diagram showing a state in which the conventional door is closed by its own weight in the state of FIG.

도3는 본 발명에 따른 버스의 비상탈출을 위한 도어 록킹장치의 전체적인 구조를 나타낸 분해사시도이다.Figure 3 is an exploded perspective view showing the overall structure of the door locking device for emergency escape of the bus according to the present invention.

이 실시예에 의하면, 버스의 비상탈출을 위한 도어 록킹장치는 차체의 상단에 레일(20)이 고정되고 도어(10)의 상단에 고정된 롤러(11),(12)가 이 레일에 연결되어 슬라이딩되고, 또한 상기 레일(20)의 상부에 고정되는 하우징(110)과, 상기 도어(10)가 완전히 오픈된 상태에서 이 도어가 닫히는 방향으로 롤러(11),(12)에 접하여 하우징에 연결되어 상.하로 동작되는 멈춤부재와, 상기 멈춤부재의 동작을 상기 하우징의 일측에 연결되어 제어하는 에어 공급튜브(130)로 구성된다.According to this embodiment, the door locking device for emergency escape of the bus has a rail (20) fixed to the top of the vehicle body and the rollers (11) and (12) fixed to the top of the door (10) are connected to this rail. The housing 110 is slid and fixed to the upper portion of the rail 20, and the rollers 11 and 12 are in contact with the housing in a direction in which the door is closed with the door 10 fully open. It consists of a stop member which is operated up and down, and the air supply tube 130 is connected to one side of the housing to control the operation of the stop member.

상기 하우징(110)은 양측이 차체에 볼트로 고정되는 고정공(111)이 형성되고, 일측에 에어 공급튜브(130)와 연결되는 공기 흐름라인(112)이 멈춤부재(100)와 간섭되는 단턱(113a)이 형성된 슬라이드 공(113)과 내통한 구조를 갖는다.The housing 110 is formed with fixing holes 111 fixed at both sides with bolts on the vehicle body, and at one side, an air flow line 112 connected to the air supply tube 130 interferes with the stop member 100. It has a structure in which it communicates with the slide ball 113 in which 113a was formed.

상기 멈춤부재(100)는 상단에 상기 슬라이드 공(113)의 단턱(113a)이 걸리는 환형의 돌기(121a)가 형성되고 하단에는 도어가 열리는 방향으로 롤러에 접하는 일측면은 라운딩되고 도어가 닫히는 방향으로 타측면은 롤러가 걸리는 걸림턱(121b)을 구비한 스톱퍼(121)와, 상기 하우징의 슬라이드 공(113)에 삽입되어 하부 방향으로 소정의 힘이 가압되도록 스프링(122)이 탄지되어 캡(123)으로 고정된 구조를 갖는다.The stop member 100 is formed with an annular protrusion 121a on which the stepped portion 113a of the slide ball 113 is caught at an upper end thereof, and at one side thereof, the one side contacting the roller in the direction of opening the door is rounded and the door is closed. The other side is a stopper 121 having a locking jaw (121b) that the roller is caught, and the spring 122 is supported to be inserted into the slide ball 113 of the housing to press a predetermined force in the downward direction cap ( 123) has a fixed structure.

도4a 및 도4b는 각각 상술한 도어 록킹장치의 조립되어 차체에 설치된 상태를 나타낸 측면도 및 정면도이다.4A and 4B are side and front views, respectively, illustrating the state in which the door locking device is assembled and installed in the vehicle body.

상슬한 구조를 갖는 버스의 비상탈출을 위한 도어 록킹장치에 의한 비상시도어의 록킹과정을 도5a 및 도5b를 참고로 설명한다.The locking process of the emergency door by the door locking device for emergency escape of the bus having a sharp structure will be described with reference to FIGS. 5A and 5B.

평상시에는 도5a에 도시된 것과 같이 에어 공굽튜브(130)를 통해 고압의 공기가 하우징(110)내 공기 흐름통로(112)로 유입되면서 스프링(122)의 탄성보다 상대적으로 큰 힘으로 스톱퍼(121)를 밀어올린다.Normally, as shown in FIG. 5A, the high pressure air is introduced into the air flow passage 112 in the housing 110 through the air bend tube 130, and the stopper 121 has a relatively larger force than the elasticity of the spring 122. Push up).

이 상태에서는 도어(10)가 레일(20)을 따라 슬라이딩 되면서 개폐되는데 스톱퍼(121)에 의해 아무런 저지를 받지 않게 된다.In this state, the door 10 is opened and closed while being slid along the rail 20, but is not blocked by the stopper 121.

도5b는 비상시 상태를 나타낸 것으로, 에어 공급튜브(130)로부터 고압의 공기 공급이 중단으로 스톱퍼(121)는 스프링(122)의 반발탄성에 의해 외부로 돌출된다.Figure 5b shows an emergency state, the stopper 121 is projected to the outside by the resilience of the spring 122 as the supply of high pressure air from the air supply tube 130 is stopped.

이 상태에서 비상레버를 수동의 위치로 조작한 후 도어(10)를 열면 롤러(11)(12)가 스톱퍼(121)의 라운딩면을 밀어 올리면서 통과하나 반대로 닫치는 방향으로는 걸림턱(121b)에 걸려 더 이상 이동할 수 없다.In this state, when the emergency lever is operated to the manual position and the door 10 is opened, the roller 11 and 12 pass while pushing up the rounding surface of the stopper 121, but in the direction of closing, the locking step 121b ) Can no longer be moved.

따라서 도1에 도시된 것과 같은 버스의 정차시에도 한 번 열린 도어는 스톱퍼(121)에 걸리게 되므로 자중에 의해 다시 닫치는 일이 발생하지 않게 된다.Therefore, even when the bus stops as shown in FIG. 1, the door once opened is caught by the stopper 121, so that closing by the own weight does not occur again.

그리고 비상레버를 자동의 위치로 조작한 후 에어 공급튜브(130)를 통해 다시 고압의 공기를 하우징내로 공급하면 도5a에 도시된 상태로 복귀되면서 도어(10)의 자동개폐가 가능해진다.When the emergency lever is operated to an automatic position and then the high pressure air is supplied into the housing through the air supply tube 130 again, the door 10 is automatically opened and closed as shown in FIG. 5A.

상술한 작용으로 본 발명은 경사면을 등판하는 위치에서 도어의 수동 조작시 도어의 자중에 의한 닫힘을 방지함으로써 승객이 짧은 시간에 도어를 통해 안전하게 탈출할 수 있도록 해 준다.By the above-described action, the present invention prevents the door from closing due to its own weight during manual operation of the door at the position of climbing the inclined surface, so that the passenger can safely escape through the door in a short time.

또한 구조가 간단하고 장착 및 탈착이 용이하고 작업성이 좋으며 반 영구적으로 사용할 수 있는 이점이 있다.In addition, there is an advantage that the structure is simple, easy to install and detach, good workability and semi-permanent use.
